Wastewater Back-up Relief Valve Installation Guide
All new construction in Lakeway MUD requires a wastewater backup relief valve. There are only a few considerations when installing a relief valve. McComis & Co. will inspect the final installation and require correction if these instructions are not followed, so please follow them carefully. The location for installing the relief valve is in the top of the cleanout just outside the home. Simply remove and discard the threaded plug from the cleanout and screw in the relief valve. That’s it.
The following items are very important. Make sure that the relief valve location is:
- Below the slab elevation of the lowest floor
- At least six inches above the soil
- Not in an area which can be flooded
After the relief valve is installed, it will be inspected as part of the normal inspection services. Call I.O. Inspections when the installation is complete, at 512-770-5534. We must insure that the installation will be effective for preventing backups and that no rainwater run-off can enter the wastewater collection system through the relief valve. We will require correction if these steps are not followed. If these steps are not followed properly, the District will notify you of non-compliance stating possible termination of water services until the installation is correct.
Thank you for your cooperation. We hope that this relief valve can prevent a disaster!
